HIYRON T. BAIRD, OF ST. LOUIS, MISSOURI.

GOVERNOR FOR AUTOMOBILE-ENGINES AND THE LIKE.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed June 25,1913. Serial No. 775,672.

To all whom it may concern Be it known that I, MYRON T. BAIRD, a citizenof the United States, residing at the city of St. Louis, State ofMissouri, have invented certain new and useful Improvements in.Governors for Automobile-Engines and the like, of which the following isa specification. v

ThlS invention relates to governors for automobile engines and the like,and has for its object to provide a governor, which is adapted to.control the throttle-valve of the engine in such manner as to preventthe latter from running faster than a predetermined speed.

Another object of the present invention resides in the provision ofmeans for adjustably setting the governor for various speedsoftheengine.

A further object of the present invention resides in the provision ofmeans for controlling the governor from the drivers seat.

A still further object of. the present invention consists in theprovision of means to insure the positive operation of thethrottle-valve in case of the'failure of the governor to effect itsoperation.

Further, the present invention consists of the novel featuresofconstruction and arrangement of parts hereinafter more fully describedand pointed out in the claims.

In the accompanying drawings forming part of this specification, inwhich like numbers of references denote like parts wherever they occur,Figure 1 is a side'elevation of an automobile engine with a governor-em-- bodying the present invention in connection therewith; Fig. 2 isatop plan. view of same; Fig. 3 is a top plan view of the lever foradjustably setting the governor from the drlvers seat Fi 4 isa sideelevation on the governor, showing alternate forms of arran ement-of thesprings; Fig. 14 is a side e evation of the form of the inventiondepicted in Fig. 13; and;F1g. 15 is a detailed view of the lever used inthe form of the invention depicted in Figs. 13 and 14.

The base 1 of the governor may be bolted or otherwise secured tothecasing of the engine 2', as depicted in Figs. 1 and 2, or it may besecured to the chassis or any other part (not-shown in the drawings)" ofthe automobile. A pillow-block 3 borne by the base 1 hasannular recesses4 in its ends for the reception and retention ofa pair of ballbearings5, and may have an oil-cup 5 or a plurality of such oil-cups fastenedthereto for the reception of a lubricant for said ball-bearings. Eachball-bearing 5 consists of an outer ring 6 having a raceway 7 in itsinner face, an inner ring 8 having a raceway 9- in its outer face, andballs 10 traveling in said raceway. Lugs ll-borne by a ring 12' arespaced apart to separate the balls 10 and have depressions or recesses13 in their opposite faces to receive said balls A hol low shaft 14extends through the inner rings 8 and has a sleeve 15 revolubly fittedthereon within the bore 16 of the pillow-block 3,

in order to hold the inner rings 8 of theball-bearings 5 in spacedrelation, said bore being preferably relatively larger than said sleeve.One end of .the shaft 14 is preferably screw-threaded to fit in ascrew-threadedopening in a member 17, which is located adjacentto therear end of the pillow-block 3 and is held firmly on said shaft by a pin18 or other suitable means, so as to rotate therewith, and the other endof said shaft has a pulley 19rigidly mounted thereon, said pulley beingpreferably grooved and being driven by a belt 20, which receives itspower from apulley 21 on the drive shaft 22: ofthe engine 2. A pair oflevers 23 is v pivotally attached to and between the walls 24 of themember 17 by pins 25 or the like.

.Each lever 23 is provided with an arm 26,

which extends between the walls 24 of the member 17 and engages the head27 on the rear. end of a rod 28, the latter extending longitudinallythrough the hollow shaft 14. A centrifugal weight 29 borne by the outerend of said lever 23 may fit on a reduced 1 portion 30 of the latter andbe held thereon ward end of then'od 28 inthe manner. hereinafterdescribed tends to force the rod rear: wardly and thereby causes thehead 27 of same to press rearwardly against the arms 26 of the levers.23, whereby the levers 23 moves the centrifugal weights inwardly towardeach other, such movement of said levers being limited by the engagementof same with the ends of themember 17, as best seen in Fig. 5.

The pulley 19 is located adjacent to the forward end of the pillow-block3 and is preferably provided with an annular recess 33 in the rear sidethereof for the reception of the rings or washers 34 of a ballthrustbea'ring. This-ball thrust-bearing preferably consists of threerings or washers 34, which are revolubly mounted on a reduced portion 35of the hub. of the pulley 19, one ring or washer 34 bearing against'thefor- Ward ends of the rings 6 and 8 of the ballbearing 5 in theforward-end of the pillowblock 3, another ring or washer 34 hearingagainst a shoulder 36 on the reduced portion of the hub of the pulleyI9, and, the third or middle ring or washer 34 having a plurality ofballs 37 revolubly supported in openings 38 thereiny The balls 37 arelarger in diameter than the thickness of'the middle ring or washer34"and bear against the other two rings or washers 34.

The forward end ofthe rod 28 is preferably screw-threaded and fits in ascrewthreaded opening in a member 39, being held securely'in said openinby a pin 40 or other suitable means. rearwardlyprojecting annularextension 41 borne by the member 39 extends into an annular space orrecess 42 between a'forwardly-projectin annular extension 43 of thepulley 19 and a forwardly-projecting extension 44 of the hub of saidp'ulley,'being provided with a longitudinal groove 45 to receive aspline46 borne by the extension 44, so that said reduced portion 49 of themember 39- and has a plurality of balls 50 revolubly su ported. inopenings 51' therein, which, ba s bear against the faces of the othertwo rings or washers 48, one of the latter'being,

also, revolubly mounted on said. reduced portion 49 and the other beingrevolublymounted on the reduced rear end 52 of a shaft 53, which isreciprocatively'moun'ted in a'bearing 54 borne by the base 1 and islocated in substantially axial alinement with the shaft 14. The shaft 53is preferably hollow, its rear end being closed and its forward endhaving a plug 55 secured therein by a pin 56 or other suitable means. Abolt or screw 57 or the like, which fits in a screw-threaded opening inthe bearing 54,-

projects into a longitudinal slot 58 in the shaft 53 and'prevents rotarymovement of the latter. A shoulder 59 onthe rear end of the shaft 53 isadapted to. engage the rear end of the bearing 54 and thereby limits theforward movement of said shaft.

In order to prevent the reciprocatory movement of the member 39 frombeing interfered with by the compression of air withinits extension 41or within the extension 43, suflicient space is left between the 1spline 46 and the walls'of the groove 45 to allow the interior of theextension 41 to extension 43, and suihcient'sp'ace is left between theperiphery of the sleeve 47 and the inner wall of the extension 43 toafford communication between the recess 43 and the atmosphere.

A lever 60 extendsthrough a transverse slot in the outer end of theplug55 and is secured at substantially the middle to said plug by a pin61 or other suitable means. A link 62, which may be pivotally attachedat 63 to the middle of the lever 60,'is connected to the operating lever64' of the throttle-valve within the carbureter 65 for the purposehereinafter described. The forward ends of a pair of links 66 arepivotally connected to the endsx67, respectively, of the. lever 60, andthe rear ends f'of said ,links are pivoted to and between the prongs 68of the bifurcated ends of two levers 69 by pins 70 or the like, saidlevers 69 being rigidly mounted on a shaft 71, which is journaled in atransverse opening in the base 1, and being located on opposite sides ofsaid base. One of the levers 69 is preferably in the form of a bellcrank having a slotted arm 72. An anti-friction roller 73 fits in theslot 74 in the arm 72, and is revolubly mounted on a in or bolt 75 towhich an end of a spring 6 is attached, the other end of said springbeing attached to the end 77 of an arm or projection 78, which may beborne by the bearing 54 The slot 74 is preferably arcuated and isarranged so that its forward end or eater part extends forwardly fromthe line through the axis of the shaft 71 and the end 77 of thecommunicate with a recess 43 within the;

arm 78, and its rear end orlesser part extends rearwardly from saidline. By this arrangement, when the pin 75 stands in a position in frontof the line through theaxis of the shaft 71 and the end 77 of the arm78, the spring 76 will rock the shaft 71 counter-clockwise, Figs. land4, and thereby cause the levers 69 to pull the links 66 rearwardly,which links, in turn, force the shaft 53 rearwardly, with the result, of

causing the link 62 to move the operating.

lever 64'of the throttle-valve to the posit1on to open to the fullestextent the communication between the carbureter and the engine cylinderor cylinders, but, when the, vpin 75 is moved to a position behind saidIt should be understood that, when the" shaft 53 moves from its extremerearward position to its extreme forward position, it

moves the operating lever .64 of the throttle valve from the position,in which the throttle-valve establishes the greatest communication',between \the carburetor and the engine cylinder or cylinders for thehighest speed of the engine, to the position, in

which the throttle-valve establishes theleast communication between the"carbureter and the engine cylinder or cylinders for the lowest speedofthe engine.

It will be evident that, when the pin 75 is moved forwardly in the slot74 away from the shaft 71, the pull of the spring 76 will cause the pullof the levers 69 upon the links 66 to increase, thereby causin thepressureof the rear end of the she 53 against the forward end of the rod28, through the medium. of the member 39 and the ball thrust-bearingcomposed of the rings or washers 48 and. the balls 50,-to increase,with, the result that the head 27 of said rod increases its pressureagainst the. arms 26 of the levers 23. After the pin 75 has been set ina predetermined position in front of the line through the axis of theshaft 71 and the end 77 of the arm 78 in the manner hereinafterdescribed, the pull of the spring 76 holdsthe shaft53, rod 28,v andlevers 23 normally in the positions depicted in Fig. 5,*whereby the link62 holds the opcrating lever-64 of the throttle-valve in position toopen to the fullest extent the communication between the latter and theengine cylinder or cylinders. After the engine 2 has beensetin..operat1on, the shaft 22 drives the shaft 14 through theintermediation of the pulleys 21 and 19 and belt 20 and thereby rotatesthe member 24, and Whenever the speed of the engine shaft 22 )ecomessufficient to cause the centrifugal weights 29 to moveoutwardlysufiiciently to cause the arms 26 of the lovers 23 to overcomethe rearward pressure of the head 27 of the rod 28 against said arms 26,the latter will force the rod 28 forwardly and thereby cause the shaft53 to move forwardly, with a the result of causing the link 62 to movethe operating lever 64 of the throttle-valve to a position to diminishthe communication between the carbureter and the engine cylinder orcylinders. This diminishing of the communication between the carbureterand the engine cylinder or cylinders result in decreasing the speed ofthe engine, as will be obvious. In this way, the governor controls thecommunication between the carbureter and the engine cylinder orcylinders so' as to prevent the engine from running faster than apredetermined speed.

Inorder to set and hold the pin 75 in anv desired position i1 1 the slot74 of the bellcrank lever 69, the former may be operated from thedrivers seat of the automobile by mechanism now to be described. Theforward end of a link 79 is preferably pivoted to and between the prongs80 of the bifurcated end of a member 81 by a pin 82 or other suitablemeans, which member is secured to the pin 7 5, and the rear end of saidlink is connectedto the end of an arm'83 on shaft 84 by means of auniversal joint 85, said shaft being journ'aled in a bracketbearing 86,which may be supported by the dash-board 87 or other part of theautomobile. A segmental gear 88 on the shaft 84 meshes with a pinion 89on the lower end of shaft 90, the latter extending upwardly through thesteering post 91 and having a lever 92 secured to its upper end for thepurpose of rotating samef Movement of the lever 92 in either directionefi'ects movement of the pin 75 in the slot 74 through the intermediaryof shaft 90, pinion 89, gear 88, arm 83, and link 79, clockwisemovement,

Fig.- 1, of said lever causing the pin 75 to move forwardly in the slot74, and reverse movement of said lever causing the pin 75 to moverearwardly in said slot. As a means for holding the lever 92 in a setposition, same has a spring-controlled latch 93 piviotally or otherwiseattached thereto, which latch is adapted'to seat in a notch 94 in theperipheral edge of a sector 95 supported by the steering post 91, therebeing a plurality of such notches in said sector. The notches 94 arepredeterminedly and accurately spaced apart so that, when the'lever 92occupies a position in which the latch 93 seats in the first notch 94,as depicted in Fig. "2, the pin 75 will stand near'the shaft 71, infront of the line through the axis of said shaft and the end 77 ofthearm 78, whereby the pull of the spring 76 will allow the centrifugalweights 29 to force the rod 28 forwardly and thereby move the shaft 53forwardly, as hereinabove described, with the result that the link 62moves the operating lever 64 of thethrottle-valve'to the position inwhich the minimum communication is established between the carbureterand the engine cylinder or cylinders, so that the enginewill drive thecar at a predetermined low speed. As long as the pin 75 remains inthis'position, the engine is preventedfrom driving the car faster thanthe predetermined lowspeed.

When the lever 92 is lIlOVGdlZO the position in which the latch 93 seatsin the second notch 94, the pin 75 will be moved farther forwardly inthe slot 74, whereby the pull of the spring, 76 will allow thecentrifugal weights 29 to force the rod '28, shaft 53, and link 62forwardly to such extent that the forwardpressure of the arms 26 of thelevers 23 becomes equal to the rearward pressure gfs the shaft 53, withthe result that The link 62 moves the operating lever 64 of thethrottle-valve to the position to establish a greater communicationbetween the carbureter and the engine cylinder or cylinders than for thelow speed of the car, thus permitting the engine to drive the car at ahigher speed than the low speed and, also, preventing the engine fromdriving the car faster than the predetermined higher speed as long asthe latch 93 seats in the second. notch 94. Moving the lever 92 to theposition in which the latch 93 seats in the third notch 94 moves the pin75 still farther forwardly in the slot 74 to its extreme forwardposition, whereby the pull of the spring 76 holds the shaft 53 in itsextreme rearward position and thereby causes the link 62 to hold theoperating lever 64 of the throttle-valve in the position to establishand maintain the maximum communication between the carburetor and theengine cylins der or cylinders as long as the latch 93 seats in thethird notch 94, thus permitting the engine to drive the car at thehighest speed; It should be understood that any number of notches ,94may be formed in the peripheral edge of the sector 95, or any othersuitable means may be employed to hold the lever 92 in predeterminedpositions for various speeds of the car.

A stop 96, which may be slidably mounted on the sector 95, is held by aspring 97 normally in the position to engage the lever 92, when thelatter is in the low speed position, i. 6., in the position in whichthelatch- 93 seats in the first notch 94. This stop 96 facilitates thecentering of the lever 92 in its low speed position so that the latchwill readily enter the first notch 94. In case the centrifugal weights29 fail to establish the minimum communication between the carbureterand the engine cylinder orcylinders when the lever 92 is moved to itslow speed position, such minimum communication can be effected by movingthe lever 92 from its low speed position counter-clockwise, Fig. 2,against the stop 96, thereby moving the pin rearwardly from its lowspeed position in the slot 74 to a position behind the line through theaxis of the shaft 71 and the end 77 of the ar 78, whereby the spring 76rocks the shaft 'i l clockwise, Figs. 1 and 4, which shaft, in turn,causes the levers 69 to move the shaft 53 forwardly through the mediumof links 66 and lever 60, with'the result of causing the link 62 to movethe operating lever 64 of the throttle-valve to the position toestablish the minimum communication between the carburetor and theengine cylinder or cylinders. Release of the lever 92 permits the spring97 to restore the former to the lows eed position.

It should be understood that, instead of the shaft 14 being driven fromthe engine shaft 22 through the medium of the pulleys 19 and 21 and belt20 as hereinabove described, gearing, 'chain-and-sprocket drivingmechanism, or any other suitable power transmitter (not shown) may beemployed to drive the shaft 14 from the engine shaft 22. c

l In the alternate form of the invention depicted in Figs. 8 to 10,inclusive, the spring 76, levers 69, and links 66 are omitted entirely,and the following mechanism is pro- 1 vided in lieu thereof. The ends ofthe lever between the prongs 99 of the bifurcated ends of a pair oflevers 100 by means of pinslOl or the like, said levers beingrigidly'inountedvon the shaft-71,. "Another lever 102 rig idly mountedon the shaft 71 has the forward end of a link 103 pivotally connectedthereto bya pin 104 or other suitable means, the rear end of said linkbeing pivotally connected to the forward end of the link '7 9 by meansof a pin 105 or the like. By this arrangement, movement of the lever 92rocks the shaft 71 through the intermediary of shaft 90, pinion 89, gear88, shaft 84, arm 83, links 7 9 and 103, and lever 101 and therebyregulates the tension of the springs 98 to increase or decrease therearward pull of said springs upon the shaft 53, thereby increasing ordecreasing the rearward pressure of the rod 28 for the purpose ofadjusting the position of the operating lever 64 of the throttle-valveto control the speed of the car in the manner hereinabove described.

In order to facilitate the rocking of the shaft 71 to adjust the tensionof the springs 98, a bell-crank 106 is pivoted at 107 to an extension108 of the bracket 86, the arm 109 of said bell-crank being providedwith a slot 110 to receive a pin 1 11 borne by a member 112, which issecured to the link 103, and the other arm 113 of said bellcrank being,also, provided with a slot 114, which has a pin- 115 reciprocativelymounted therein and is preferably arcuated as shown in Fig. 8. A spring116, which is attached at one end thereof to the pin 115 and at theother end to a bracket 117 secured to the dash-board 87 or other part ofthe automobile, tends to rotate the bell-crank 106 clock-- wise, Fig. 8,and thereby dauses the arm 109 to pull rearwardly upon the pin 111sufliciently to balance or nearly balance the pull of the springs98. Arod 118 pivotally attached at one end to the pin 115 and at the otherend to the link 103 moves with the latter and thereby moves the pin 115in the slot 114. By this arrangement, whenever the lever 92 ismoved fromits low speed position to a position to permit the engine to drive thecar at a higher speed, the arm 83 pulls the link 103' rearwardly throughthe medium of link 79,v whereby said link 103 not only rocks the shaft71 counter-clockwise-to increase the tension of the springs 98, but,also, causes the rod 118 to move the pin 115 farther away fromv thepivot 107, with the result of-increasing the pull of the arm 109 uponthe pin lll sufliciently to balance or nearly balance the pull of thesprings 98. In this way, the spring 116 facilitates the moving of thelever 92.

In Figs. 11 to 15, inclusive, three alternate forms-of the means forregulating the rearward pressure of theqshaft 53 are depicted.-

In Fig. 11, a spring119, which is coiled about a portion of the shaft71, has one end attached to the lever'102 and the other end attached toone of the levers 100 and tends to rock the shaft 71 in the direction tocause the links 66 to pull the'shaft 53 rearwardly, the lever 102, inthisrarran ement, being revolubly mounted on the sha 71 and beingconnected to the link 103, so that same can be adjusted from the driversseat, in the manner hereinabove described; to increase or decrease thepull of the spring- 119 for various speeds o the car. Inthe' formdepicted, on Fig. 12, the lever 60 is omitted entirely and the link 62is connected -to the plug 55 by a pin 120. The shaft.53 is relativelylonger and has a member 121 reciprocatively mountedon the forward partof same, a spring 122 being interposed between said member and a collaror shoulder 123 on shaft 53. The forwardrends of the links 66 arepivotally connected to the ends 124 of the member 121, and the lever 102is rigidly mounted on the shaft 71, so that movement of the link103willcause the lever 102 to rock the shaft 71, which, in turn, effectsmovement of the member 121 through the medium of levers 100 and links66, with the result of adjusting the rearward pressure of the spring 122upon the collar or shoulder '123 on the shaft 52 to control the speed ofto the engine or any other suitable part of the automobi e. A spring 127is attached to the other end of the lever 125 and, also, to an end of alever 128, which is pivoted at 129 to an arm or projection 130 ofthevbase 1. The other end of the lever 128 is bifurcated, its prongs 131straddling the forward part of the shaft 53 and being pivotallyconnected at 132 to the rear ends, respectively, of the links 66, andthe forward ends of'said links being pivoted to the ends 67 of the lever60. One of the prongs 131 is relatively longer than the other prong andhas the link 62 pivoted at 133 to its end. By this arrangement, the pullof the spring 127 tends to rock the lever 128 counterclockwise, Fig. 13,and thereby causes the links 66 to pull the shaft 53 and link 62rearwardly. Movement of the link 103 in the manner hereinabove describedeffects adjustment of the spring 127 for the various speeds of the car.It will be observed that, by reason of the link 62 being farther awayfrom the pivot 129 than the links 66, move ment of the shaft 53 efiectsa relatively greater movement of the link 62.

One great advantage arising from the use of the governor hereinabovedescribed is that the necessity and expense of using differentialgearing to control the various speeds of the car are obviated. The operation of the governor will be readily understood from the foregoing, andneeds no further description.

Various changes in the construction and arrangement of part may be madewithout departing from the nature and scope of the present invention.
